(c1. :w-254i 2 Claims.

This invention-relates toshears and scissors (hereinafter collectively referred toas shearsW and has for an object the'provision of fa pair of shears whos'eblade and handlemembers and intermediate side portions can be stamped out of appropriate sheet metal in. accordance with acceptedstamping methods and standards.

A further object is theprovi'sion of a pair of `shears whose constructional fea-turesfwould lend v themselves to `faster and cheaper methods of production. .s

A still further object is the provision of a pair of shears whose constructional featuresvare `such pensed with in its manufacture. f I

Another object is the provision of a method of making such shears consisting of stamping its blade and handle members and intermediate side These and other objectsare attained bythe simple device of making thebla'de and handle members and intermediate side portions of,V four parts instead of theusual two and of riveting each complete unit together. Each of the four parts comprises an element of such shapeA that it might readily be stamped yout in the usual way using the usual ,stamping means. Heretofore the shoulder e' at the point where the handle member ends and the intermediate side portion'begins has been the stumbling block to elo'ts directed toward stamping the blade and handle members and intermestacle is eliminated in the device herein disclosed since here the shoulder'portion has been made integralwith only half of the handle member, this shoulder halfbeing wholly separate and apart two p arts hereinabove mentioned, namely, the

part comprising the shoulder portion and the shoulder half of the handle;

Figure 4 is a similar view'of both said parts showing how the part shown inV Figure 3 is mounted on and fastened tothe part'l shown in that the usual forging operation may beV disdiate side portions out of sheet metal.A This obfrom the other half of the handle member'which is integral Withthe intermediate side portion and with the blade member. Each of these partsthe shoulder and shoulder half of the handle on the one hand, and the other half'of` the-han'dlaY intermediate side portion, and bladey on the other hand-is of such thickness and such proportions that it can readily be stamped out of an appropriate sheet of metal. v

A preferred embodiment of the invention is illustrated in the accompanying drawing in which- Y Figure 1 is a sideelevation of a vsmall pair of 'Figure 2;

Figure 5 is a bottom or bottom edge view of the unit shown in Figure 4; and

Figure 6 is anvenlarged section on the line 6'6,.

Figure 4.

The shears shown comprises two pivoted and cooperating members each consisting of. one of the two blades I0, one of the two intermediate side portions II and one of the two handles I2.

AThe two parts are pivotedftogether bya rivet or other suitable pivot I3. rAs shown in Figures 4 and 5 each of these members vconsists of two parts riveted together by means` of f rivets I4. The smaller of these parts lis shown in Figures 3 and 5 to consist of one half I5 ofthe handle I2 and the shoulder I6. The bigger of these parts lis shown in Figures 2 and 4 to consist of the other half I1 of the handle I2, the intermediate side portion II and the blade Ill. Handlev parts I5 and I l are substantially identical in-every respect 'constituting, as they do, the two sides of each handle I2.

The unit comprising blade I0, side portion II and half Il of the handle I2 can readily be v stamped outyof a at sheet ofmetal since the unit is itself a substantially flat unit of like thickness its cutting edge I8). The unit comprising the shoulder I6 and the half I5 of the handle I2 ris also e a flat unit of like thickness throughout and can shears (commonly known as scissors) of thecony struction herein described, lthe bladesbeing shown in closed position;

Figure 2 is a similar view of one of the two parts hereinabove mentioned, namely, the part also readily be stamped out of a flat sheet of metal. e

It should be noted that handle parts I5 and I6 need not have the same. thickness. It is suiicient if part 'I5 is asthick as shoulder IB is highwhatever that height may be. In other words part I5 is to be stamped out of a sheet of metal as thick as the shoulder I6 required to befhigh.

It is apparent-.that the invention shown above has been given `by way of illustration and not by way of limitation, and that the illustration shown above is capable of wide variation and modification Within the scope of the present invention.

-All of such variations and modifications are to be What is claimed is:

1. A shear comprising two pivoted and cooperating members, e-ach consisting of a blade, an intermediate side portion and a handle, each of said members comprising two substantially flat t parts affixed to one another.

2. In a shear of the character described, a handle comprising two substantially iiat parts, one of said parts being integral with one of the intermediate side portions and one of the blades and comprising half the handle, the other being integral with the shoulder located at the point where the handle and the intermediate side portion meet, and comprising the other halfof the handle, said parts being affixed to one another by means of rivets.
